Good afternoon all, just finished countersinking the holes in the RSP. I have the 1919 all mocked up, rivets in place and I have one long skinny rivet left, what is it for? I have the two thick long rivets going through the trunnion, the one long skinny one going through the pintle pad and trunnion, and the other one going through the hole that is directly behind the top cover. So where does this third long skinny one go???
